Algorithm

Selection

Set1

All the <a> tags with a “href” attribute, without children (a[href]:not(:has(*)) )

Set2

All the elements of Set1 with a not empty text and with a title attribute

Process

Test1

For each element of Set2, we check whether the “title” attribute is not empty

For each element returning false in Test1, raise a MessageA

Test2

For each element of Set2, we check whether the “title” attribute doesn’t only contain non alphanumerical characters.

For each element returning false in Test2, raise a MessageB

Test3

For each element of Set2, we check whether the “title” attribute value doesn’t belong to the text link blacklist.

For each element returning false in Test3, raise a MessageB

Test4

For each element of Set2, we check whether the “title” attribute is not strictly identical to the link text.

For each element returning false in Test4, raise a MessageB

Test5

For each element of Set2, we check whether the “title” attribute contains the link text and more.

For each element returning true in Test4, raise a MessageC

For each element returning false in Test4, raise a MessageD
